Do A For ... Each Loop Backwards?

I don't believe this is possible by conventional methods, but something like this verbose code: For Each s As String In myStringList Step -1 //' Do stuff here Next I will probably have to invert the myString object before a conventional For..Each Loop, correct?

Autonumber From Database Is Going Backwards

Apr 17, 2009

Does anyone know of any reason why my FilmID field (which is an autonumber) is going backwards? When I add a new record, it is going -1, -2, -3, -4, instead of carrying on from the last number. If you need the code, just ask, but I was thinking it might be something in properties or something?

.net - WebBrowser.Refresh - Navigate Backwards

Apr 20, 2009

I'm working on a webcrawler in VB.net, and using the System.Forms.WebBrowser object for handling navigation on sites that use javascript or form posts, but I'm having a problem. When I navigate backwards (WebBrowser.GoBack()) to a page that was loaded with a form post, the page has expired and I have to do a refresh to resend the request. When I call a refresh (WebBrowser.Refresh()), a dialog box pops up to confirm. Is there a way I can get around this modal dialog in code?

Read Text File And Stop Then How To Continue At The Last Read Point

Dec 15, 2009

I'm using vb.net 1.1 to develop the program. I got text files that contain test result from a machine, like below.

T1 1.24535 2.56335 2.43253 1.24538 2.55619 4.35243
T2 1.42542 1.63728 3.57295 4.59275 1.57320 2.72057
T3 5.12857 2.45375 6.38593 2.58375 3.57259 3.57204

I need to check the test result with the data from database, to find out which test result is failed. If there is a fail test result, I will show an alert to the operator and stop the checking process. Until the operator close the alert, then the checking process will continue from the last read point.

C# - Open A Read Only File As Non Read Only And Save/overwrite?

Sep 21, 2011

I have a number of word documents I am converting. Everything is going great until I get a file that is read only. In this case I get a Save As prompt.

Is there any way to open the file in read/write format? I should have admin privileges so access isn't an issue.

I'm using VB.net to open the files. More specifically

doc = word.Documents.Open(path, Type.Missing, False, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing)

File I/O And Registry :: Binary File Primer - Read The Nth Record Without Reading The Whole File?

May 4, 2009

I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.

Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file

Some specific questions:

Does the record length have to be constant throughout the file?

Can I read the nth record without reading the whole file?

Read XML File - Read The Data From ?

I have a fairly simple XML file that I just want to read the data from.

It has 3 levels, root, main section and items. There are no attributes. I want to go to the first main section by name, then read in all the items. The items all are named the same. I've seen this done before, so it should be ok. No writing will be done. Basically this is a static data file

AxMediaPlayer Step Function Doesn't Step Backwards

Nov 10, 2011

I have a program that plays a video and uses the step function to move frame by frame backwards and forwards through the video. The forward frame works just fine:

AxWindowsMediaPlayer1.Ctlcontrols.step(1)

However, the backwards step (below) jumps a full second backwards while the forwards step only steps .033 seconds forward (presumably a single frame).

AxWindowsMediaPlayer1.Ctlcontrols.step(-1)

I can't find any documentation about this problem online and in fact I can't find much mention of this function.the documentation does say the -1 command should step back one frame. IWMPControls2::step method Is this a known bug or is there an updated function I should be using?

File I/O And Registry :: Open / Read Binary File / Care To Check Code?

Jun 14, 2009

I've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.

Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.
